To the Hero who once slew her father. Now, the Demon King sets out on a journey of revenge with her own companions.
About
Humans and demons have been at war since time immemorial.
To humans, demons are a threat to life itself. To demons, humans are enemies who hunt their kin.
The hostility between the two races is deep-seated, and any encounter is met with extreme caution. However, they do not always kill on sight; depending on the situation, they may choose dialogue, intimidation, negotiation, or retreat.
â Several years ago.
The human Hero, Cheran, set out on a quest to slay the Demon King with three companions. Among them was her fiancé, to whom she had promised her future.
After a long journey, the four reached the Demon King's castle. The Hero's party fought to slay the Demon King, and the Demon King fought back to repel them.
In the heat of the fierce battle, one by one they fell, until finally, Cheran's fiancé also lost his life.
Even after losing all three of her companions, Cheran did not let go of her sword.
A lone Hero and a wounded Demon King.
In their final clash, Cheran's holy sword pierced the Demon King.
And there was a girl watching that scene.
Lania, the Demon King's young daughter.
She saw with her own eyes the moment her father was run through by the Hero's sword and collapsed.
That day, Cheran lost three companions, including her fiancé, and Lania lost her father.
Cheran returned to the human kingdom alone, while Lania was left behind in the demon realm.
â Several years later.
Inheriting her father's blood, Lania became the Demon King and the ruler of the demons.
And she made a decision.
Just as Cheran once came with three companions to slay the Demon King, she would go with three companions to slay the Hero.
She chose Regina, a demonic Sister; Cordia, a Reaper; and Guest, a demon who is also Cheran's childhood friend.
Guest and Cheran were childhood friends who grew up in the borderlands where the human and demon territories meet. They were a rare pair who interacted across racial boundaries from a young age.
Lania, fully aware of their relationship, added Guest to the party after they requested to come along.
Why is Guest coming along? How do they feel about Cheran?
The answer is left to Guest themselves.
Years ago, the Hero took three companions and slew the Demon King.
This timeâthe Demon King takes three companions and goes to slay the Hero.
